'2 Claims. (Cl. 254-129) This invention relates to a new and usefulimprovement in a window opener, and more particularly to the sash of awindow that has become stuck to the window frame and cannot be opened bymanual means.

It is well known that when houses and buildings are decorated, thewindows, when painted, generally become stuck by the paint and tools aregenerally required to open them. When such devices are used, thewoodwork of the window quite frequently becomes scarred in the processof opening it.

One of the objects of this invention is the provision of a deviceadapted to open a stuck window.

Another object of this invention is the provision of a window opener soconstructed that it will not mar or deface a window when it is used toopen such window.

Other objects and features will more fully appear from the followingdescription and accompanying drawings, in which:

Fig. l is an elevational of a window showing the application of theinvention;

Fig. 2 is a sectional side view of a window and the device appliedthereto, and taken along lines 22 of Fig. 1;

Fig. 3 is a view in side elevation of a detail of the invention with onebuffer, cushion or pad in section;

Fig. 4 is a sectional view taken along lines 4-4 of Pi 3, and

Fig. is a sectional view taken along lines 5-5 of Fig. 4.

Referring more particularly to the drawings a stanchion or bar 1 has aresilient cushion or rubber pad 2 secured thereto in order to preventthe marring or scarring of an object it is adapted to rest upon. Acarriage 3 is provided with an aperture 4 through which bar 1 passes inslidable fashion.

A channel 5 is adapted to accommodate a lever 6 mounted in pivotalfashion upon an axle or pin 7 disposed in the sides of said channel. Thelever 6 has one of its ends 8 angular in shape and is adapted toaccommodate a resilient tip or cushion 9 to prevent the marring of anobject when force is applied by said lever against said object.

A leg 10 on said carriage has an orifice 11 therein to accommodate ahook 12. End 13 of said hook constitutes an eye and is adapted to engagebar 1 in slidable fashion. Shank 14 of the hook is smaller in diameterthan orifice 11 and a wing-nut 15 is mounted in threadable fashion onend 16 of the hook and rests upon a washer 17 that engages leg 10.

It is thought obvious that when the carriage is actuated or adjustedupwardly or downwardly towards pad 2, the hook will impinge upon or gripthe bar 1 in an angular fashion and thereby prevent verticaldisplacement with respect to the carriage and bar, and thereby lock theformer to the latter.

A window 18 consists of a casement or frame 19 provided with sashes 20and 21 that are adapted to respectively move in tracks 22 and 23, all ofwhich is wellknown in the art.

The device functions as follows: Assume that sash 20 is stuck or securedto frame 19 by paint or other adhesive material, then bar 1 has itspadded end resting upon frame 19, while the padded end of lever 6 restsor engages sash 20. Hook 12 then locks the carriage in a suitableposition for operation. Lever 6 is then forced downwardly therebyapplying force to the sash and causing it to move to an open position.

Of course, the aperture through which the stanchion or bar passes isgreater in diameter than the latter and when force is applied to thelever it also tends to move the carriage in angular fashion against thestanchion or bar and this also tends to lock the carriage thereto.

it is also to be understood that the device may be applied in transversefashion to a window.

Having described this invention, what is claimed is:

1. In a window opener of the kind described, said opener comprising abar having a carriage slidably movable and adjustable mounted thereon,said carriage having an apertured portion therein, said aperture of saidapertured portion comprising transverse dimensions larger than thetransverse dimensions of said bar, thereby providing for limited tiltingmovement of said carriage on said bar for gripping action of saidcarriage on said bar in any adjusted position of said carriage on saidbar, said carriage having walls on one side thereof defining a channel,a lever, said lever being pivoted intermediate its ends in said channelto the walls thereof, said lever havin a power arm and a weight arm,said Weight arm having on its free end a suitable pad to prevent marringof a widow sash, said carriage having on the outermost portion thereof aleg projecting therefrom, said leg having an aperture thereintransversely thereof, the axis of said aperture being at right angles tothe axis of said bar, a bolt, said bolt having one end thereof providedwith a screw thread and a threaded nut thereon, said bolt having itsother end provided with an embracing portion slidably embracing saidbar, said bolt loosely passing through said leg whereby said carriagemay be forcibly tilted into gripping action with said bar to maintainsaid carriage in any suitably adjusted position on said bar, one end ofsaid bar having a pad thereon for nonmarring contact with a windowframe.

2. In a window opener of the kind described, said opener comprising abar, a carriage mounted in slidable fashion upon said bar, a leverpivotally mounted on said carriage and having a portion thereof ofgreater length from said pivot than the remaining portion; a hook havingone of its ends engaging said carriage and the other of its ends mountedabout said bar in slidable fashion, said carriage and hook adapted togrip said bar and prevent vertical displacement between said bar,carriage and hook upon suitable and adequate lever force.
